CONVEYER.

Application filed July 6, 1925. Serial No. 41,617:

This invention relates to conveyers, and

more particularly 31101311058 in which a belt is employed to provide a supportingsurface at the required-speed, as in loading materials oficer'tain kinds-into cars, orother vehicles,-

or-for other=purposes 4 i "It is also anwobject to provide certain deadapt-ed more loader. e

To these and other useful ends the invention consists in matters hereinafter set forth andclaimed, and shown in the accompany 111g drawings, in wh1ch: 2 p r Fig. 1 is aside --elevation of a conveyer principles" of the inventions r F ig. 2 is a front elevation ofsaid loader.

Fig. 3 is a vertical-longitudinal section of said conveyor.

prises the transverse rollers 1 and 2 suitably mounted on the vbody frame 3 of the ma Thus the middle portion of the upper stretch K A of the belt is caused to operate on the line of a circle struck from the axis ofthe rollers 01- idler wheels 5, in the manner shown,

As shown, the roller 1 is preferably mounted on the body frame by means of arms 8 pivoted on the axis member 6 and held yieldingly in operative position by the springs v9 which connect the arms to the so body frame, thus keeping the belt 4 pressed yieldingly againstthe under sides of the 'idler wheels 5 previously mentioned.

' in the form of av loadefr .embodying the As thus illustrated, the invention com-.

The roller is driven by a sprocketand belt connection 10, toga, motor 11 ofanypuit able'character, so.-that the,belt WYllljbQ driven the required speed. I 7

A hopper 12 is mounted in position li body: frame 3,as shown, to delive-r the mat'erials to the belt between the :ii'pllers l and 2, but close a to theeroller 2,.so -,that the matelflalS-d willv travel ,i'downwardlyaoll the-1 belt and then forwardly and then upwardlybefore :being discharged therefrom. In pthis way, therefore the .materialsQ ,While on, the belt are :subjectedto theiaction of centrifugal: force, inasmuch as the materialsgare tails and featuresof construction and com- H binatifons tending to-incr-easev the general" -etiicie-ncy and the desirability of a conveyer particularly for use as aforced to travelonthe line of'a circle-str-ucli from the axis of themember 6,.and-Jin this Way, becausefiof. the; action wiof: centrifugal force, "the materials tend to cling to the wibelt, and almost instantly acquire ,the full speedofthebelt," Ifth-e b lt Werestraight,

it would slip" under! then-materials, and,v the latter wouldfnot. acquire the speedgofthe V-belt;..but with thebelt cUrv'edQasashOWn, so

that centrifugal: force is employed "to .aug-i iment v the gravity. pressure of ,the materials on. the. belt, it is obvious that the fliiaterials will almost immediatelygacquire theifull speed of,the.,. belt,xand will 'b'e discharged from the convey-cr m the direction indicated by the a'ITOVylIl Fig. 3,-at1the requiredspeed necessary for loading @materials .iintoI ajcar, or. for any otherpurpose v Mg,

The; entire machine is mounted on vehicle wheels 13, as shown, so .that,by;tilting the legs 14- of thebody frame off the ground,

the entire machine .canbe' moved around like a cart. Y;, J

Thus a comparatively simple and inexpensive conveyor, is provided, in the form of a loader, if desired forthis purposewvhich is comparatively light and, of less size ,than machines heretofore employed for thispurpose, and whichcanwbev movedaround in a e convenient, manner.: The arollers or idler wheels 5, being spaced apart,-as shoyvn' provide ample space between tl1em,-for..th.e discharge of the materials on ,7 to [the belt, 3 and for the conveying thereof. down'wardly, and then forwardly and then= upwardly, on the ,middle portion of thee-belt, inithe, manner shown. While the machineislin"operation,

centrifugal force tends ,to 5 keep portion use! of the belt between the idler wheels 5 frommachine is in rear of the axis of the cart flexing or rising between the two wheels -5, so that the belt is maintained in condition to run at high speed and convey the mate rials thereon in the desired manner.

The two idlers 5 form side walls for the space between them, so that materials cannot escape at the sides of the belt. It will be understood, however, that the invention is not limited to the exact construction shown and described, and that any suitable or desired construction, involving the feature of a conveying surface which travels on the arc of a circle, to subject materials to centrifugal action thereon, may be employed without departing from the spirit of the invention.

Thus it will be seen that with the two discs or idlers 5 spaced apart, to provide a large volume of space between them and above the belt, the space above the curved surface of the belt is practically unobstructed, inasmuch as the axis member 6 is of comparatively small diameter, whereby there is practically no obstruction in the space between the belt and the horizontal plane of this axis. Furthermore, the curved conveying surface of the belt'is practically entirely below the horizontal plane of said axis, and the discharge end of the curved surface is a substantial distance above the bottom of the circle of the periphery of said discs 5, so that the discharge is forward and upward. Also, the curved portion of the belt terminates at each end in the reverse curve of a smaller circle, and each smaller circle is of such diameter that a straight line tangent to the bottom of each circle is below the periphery of the larger circle of the two discs, whereby the only straight portion of said belt is that forming said tangential line. With this arrangement, the outlet of the hopper, and the hop per itself, are set low, which is important in a car loader, and the outlet of the hopper is at or close to the horizontal plane of the axis of the two discs, so that the materials are discharged practically immediately against. the curved receiving end portion of the conveying surface of the belt. The en-' tire apparatus is mounted on a pair of vehicle wheels, as explained, so that the structure can be tilted like a cart and wheeled about, and with the two portions 14: adapted to rest firmly on the ground, the cart will be held steady while the machine is in operation. The wide space between the two discs permits the use ofa large hopper set low down to reduce the height of themachine, and preventing the materials from touching anything other-than the belt and discs after leaving the hopper. The cart wheels are set forward of the center, it will beseen, and the motor is in the rear, or at least the greater part of the weight of the,

wheels, so that the rear end of the machine is weighted to hold it down when in use.

lVit-hout disclaiming anything, and without prejudice to any novelty disclosed, what I claim as my invention is 2- 1. A conveyer machine comprising means to provide a conveying surface curved on the line of a circle struck from an axis above,

so that materials carried on such surface will .be subject to centrifugal action, causing the materials to bear with greater pressure against such surface, and instrum-entalities for causing said means to have motion at the required speed about sald axis, said means and instrumentalities comprising an endless conveyer belt and a pair of idler discs engaging said belt to form the said curved conveying surface, each disc being separate from the other, a shaft on which said discs are spaced apart and secured in spaced relation to provide a space between them which is unobstructed except by said shaft, and a hopper disposed with its lower portion in said space adjacent the receiving portion of the belt, said space thus permitting the use of a hopper of the desired size and in lower position to reduce the height of the machine, and preventing the materials from touching anything other than said belt and discsafter leaving said hopper.

2. A. conveyer machine comprising means to provide a conveying surface curved on the line of a circle struck from an axis above,

so that materials carried on such surface will be subject to centrifugal action, causing the materials to bear with greater pressure against such surface, and instrumentaliti-es for causing said means to have motion at the required speed about said axis, said means and instrumentalities comprising an endless belt and two separate discs and a shaft upon which said discs are spaced apart to provide a clear space between them above the belt, rolls for said belt in front and in rear of said discs, whereby the curved conveying portion of the belt terminates at each end in the reverse curve of one of said rolls, said rolls being of such diameter that a straight line tangential to the lower side of both rolls is immediately below the conveying portion of said belt, a hopper of ample size and feeding capacity and set down low in said space to reduce the height of the machine, preventing the materials from touching anything other than said belt and discs after leaving said hopper.

' 3. A conveyer machine comprising means to provide a conveying surface curved on the line of a circle struck from an axis above, so that materials carried on such surface will be subject to centrifugal action, causing the materials to bear with greater pressure against such surface, and instrumentalities for causing said means to have motion at Ill ill

the required speed about said axis, said means and instrumentalities comprising an endless conveyer belt and means including only two pulleys to conform the belt to the curve of said surface, the pulley at the discharge end of the curved conveying portion of the belt being movable, and spring means to keep this movable pulley in position to keep the belt tight.
